I've been running it for a while, it seems to work okay. Here are the files for download, the instructions are contained in the description for each file. Eventually I should do some instructions in the Wiki, but this should be enough to get going.

This only works with the Linux Squeezeboxserver as the Windows one is precompiled so it can't be patched.

Let me know how it works for you!
